AMD Secure Processor Boot Loader OOB Write via Unsanitized Input
CVE-2025-29949 Published on February 10, 2026

Insufficient input parameter sanitization in AMD Secure Processor (ASP) Boot Loader (legacy recovery mode only) could allow an attacker to write out-of-bounds to corrupt Secure DRAM potentially resulting in denial of service.

NVD

Weakness Type

What is a Memory Corruption Vulnerability?

The software writes data past the end, or before the beginning, of the intended buffer. Typically, this can result in corruption of data, a crash, or code execution. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent write operation then produces undefined or unexpected results.

CVE-2025-29949 has been classified to as a Memory Corruption vulnerability or weakness.
